Powder coating will inevitably age after long-term use, resulting in chalking, fading, cracking and peeling, which affects the protective and decorative effects. Most users lack scientific maintenance methods, leading to premature failure of coatings. This article systematically analyzes the aging mechanisms of indoor and outdoor powder coatings, summarizes the influence of ultraviolet radiation, temperature alternation, chemical erosion and human factors on coating aging. It provides targeted daily maintenance, regular inspection and repair schemes to help users delay coating aging and maximize the service life of powder coated products.
This article focuses on particle size distribution (PSD), the core physical indicator determining powder coating quality. It systematically analyzes common particle size defects including excessive fine powder, oversized coarse particles, uneven particle concentration, and poor fluidity caused by unreasonable PSD. The article deeply analyzes the root causes from milling speed, classifier parameters, screen condition, and raw material hardness, and provides targeted equipment adjustment and process optimization schemes. It also summarizes TYOPSUN’s daily particle size control standards to help manufacturers achieve stable and qualified powder particle size.
This article introduces professional antibacterial and mildew-proof powder coatings suitable for high sanitary and high humidity environments such as hospitals, catering kitchens, bathroom facilities, and food processing workshops. It analyzes the antibacterial mechanism of inorganic silver-ion and zinc-ion antibacterial agents, explains the key points of formula compatibility and additive dosage control. The article solves common production problems such as antibacterial failure, mildew resistance attenuation, and color change, and introduces TYOPSUN’s precise mixing technology to ensure long-term stable antibacterial and mildew-proof performance of finished powder.
This article delves into nanocomposite powder coatings for powder-bed-based additive manufacturing (AM), such as laser powder bed fusion (L-PBF) and binder jetting (BJ)—a rapidly growing field in automotive and aerospace industries. It explains how nanocomposite powders (incorporating ceramic nanoparticles like Al₂O₃, B₄C, and SiC) enhance the mechanical properties (strength, stiffness, wear resistance) of 3D-printed parts. The article details the production requirements for AM powders (particle shape, size, flowability) and how TYOPSUN’s air classifying mills and mixing equipment ensure precise particle size control and uniform nanoparticle dispersion. Manufacturers can leverage this technology to produce high-performance, complex components for demanding industries.
